SoundCheck ONE for headphone testing
We are excited to announce a new low-cost headphone test package – SoundCheck ONE for headphone testing (part # 1007). This includes SoundCheck ONE, a basic version of the SoundCheck software, along with AudioConnectTM, an audio interface with built-in headphone amplifier. Only a headphone coupler or test fixture and associated power supply is additionally needed to make up a complete headphone test system. The SoundCheck ONE headphone test sequence carries out all basic headphone measurements such as frequency response, sensitivity, THD, Rub & Buzz, Perceptual Rub & Buzz, loose particles, polarity and channel balance. It can be easily customized and saved for specific products by turning individual measurements on and off, and by adjusting settings within each sequence step such as stimulus range and level, tolerance limits, graphical displays, and data saving. It is an excellent low-cost entry level system, ideal for those on a tight budget.
Please note that although the SoundCheck ONE Headphone test sequence cannot have steps added/removed or the layout modified, customers may upgrade to a SoundCheck package that supports this at any time in the future, should testing needs expand to require additional functionality. Listen can also offer the GRAS 45CC headphone test fixture along with a SoundConnect 2 power supply for a complete production line test system.

SoundCheck 15 New Features Video
In this short 10 minute video, sales engineer Les Quindipan gives a brief overview of the new features and functionality, and demonstrates them in the software.
Listen Awarded Patent for SC Amp Amplifier
Listen’s revolutionary audio test amplifier, SC Amp, has been awarded US Patent # 9,386,387. This patent covers Listen’s unique high accuracy single channel impedance measurement method, which used a unique feedback circuit to offer dual channel accuracy using just a single channel. This enables full electrical and audio tests to be carried out simultaneously and with high accuracy using just 2 channels.
Specifically designed for the audio test market, SC Amp also incorporates several other features unique to the needs of audio test and measurement, such as low distortion (THD <0.025%) and a low noise floor (>100dB). Fixed gain eliminates calibration errors as there is no gain knob to be accidentally knocked or tweaked when it is in use. It supports the application of a DC voltage offset to the AC signal for testing transducers under adverse conditions, and features overload/output protection to prevent damage in case of shorting or overload.
Many unnecessary features found in regular audio amplifiers have been eliminated to keep production line operation simple and error-proof. Although it is designed to integrate seamlessly with Listen’s SoundCheck audio test and measurement software, it will also work well with other brands of test system.
Listen president, Steve Temme commented, ‘We are thrilled that the innovative design of this product has been recognized with this patent, and we are confident that this method will be quickly recognized by the marketplace.’
Listen Releases SoundCheck Version 15
New multimeter
Listen, Inc., is excited to announce the release of SoundCheck Version 15. This release expands the testing capability of SoundCheck with additional external control, calibration, audio mixing and hardware integration, and introduces the first in our redesigned virtual instruments, the multimeter.
The redesigned multimeter now offers two views, a compact ‘meter’ view, or an expanded detailed ‘settings’ view. In ‘meter’ view, a clear, simple level meter is displayed, which changes color to warn of overload or near overload values. Averaging type, weighting type and bandwidth are also shown. In expanded view, 4 different tabs for measurement, averaging, filters and limit setting are visible, and options such as linear/log scale, filtering and weighting options, etc. can be selected. Enhancements to the multimeter’s capabilities include the ability to measure DC voltage in addition to AC voltage so that SoundCheck can be used with a DC coupled interface for making audio electronic measurements, high and low pass filters for removing electrical noise and low frequency background noise, and automatic scaling to adjusts the range of the display based on the signal.
New TCP/IP control functionality makes external control of SoundCheck simpler, yet more powerful, a valuable feature for anyone who needs to control SoundCheck from an external program, for example as part of an overall test plan or factory automation. It allows communication with SoundCheck via any programming language, on any operating system, either locally or through a network, so that a single computer can control multiple SoundCheck systems. It also features a more powerful and expandable command format for interacting with SoundCheck.
Other enhancements include accelerometer calibration and force measurement to enable testing of linear motors such as those used in haptic devices, an improved plot legend with choice of placement, faster setup with a new ‘auto-mode’ in the hardware editor, better control of Bluetooth interfaces and an improved audio mixer.
